ISRM had over 139 broken links and has had to delete most of the offending URLs across its 441 pages. Some slide rule collection have been found to be relocated and a considerable effort was made to find an alternative address on Institutional sites that were changed. If you have a slide rule site, or one to recommend, please emal the ISRM Curator with good links and they will be added to this list. Thank you!
